I tried to make a 120 GB mosaic. The error message says I need to change the max value to larger than 12GB at ~/.Isis/IsisPreferences. But there is no such file. I have no clue where to change this preference value...

History

You might need to take another look - when I look I see the file /home/laz/.Isis/IsisPreferences

If for some reason you still do not see your file you can copy the system default file into your .Isis directory and modify the MaximumSize value under the CubeCustomizaton group. The default file can be found under the $ISISROOT directory which expands to /usgs/pkgs/isis3.5.1/isis/ if your are using the public version of isis3.

I did a google search for ISIS Preference file and found an ancient discussion...
Copied the file out of $ISISROOT and all seems to be working.
But the error message might need to be rewritten or the ISIS3 installation should create a user preference file because the current error message is not sufficient.

Just to clarify - did you change the value of MaximumSize in the preference file? The default is 12 Gb and automos/mapmos/etc. will eventually fail again if it wasn't modified and may take a while to tell you so.

*USER ERROR** The cube you are attempting to create [tttt] is [14GB]. This is larger than the current allowed size of [1GB]. The
cube dimensions were (S,L,B) [380000, 40000, 1] with [1] bytes per pixel. If you still wish to create this cube, the maximum
value can be changed in the file [~/.Isis/IsisPreferences] within the group CubeCustomization, keyword MaximumSize. If you are
having troublelocating the IsisPreferences file, please refer to thedocumentation on Isis setup. A user preference file may not
havebeen created in Cube.cpp at 378.

Some of the words do not have spaces between them
